ADE7116/ADE7166/ADE7169/ADE7566/ADE7569

GENERAL FEATURES

Wide supply voltage operation: 2.4 V to 3.7 V

Internal bipolar switch between regulated and battery inputs

Ultralow power operation with power saving modes (PSM)

Full operation: 4 mA to 1.6 mA (PLL clock dependent)

Battery mode: 3.2 mA to 400 µA (PLL clock dependent)

Sleep mode

Real-time clock (RTC) mode: 1.5 µA

RTC and LCD mode: 38 µA (LCD charge pump enabled)

Reference: 1.2 V ± 0.1% (10 ppm/°C drift)

64-lead RoHS package option

Low profile quad flat package (LQFP)

Operating temperature range: −40°C to +85°C

ENERGY MEASUREMENT FEATURES

Proprietary analog-to-digital converters (ADCs) and digital

signal processing (DSP) provide high accuracy active

(watt), reactive (var), and apparent energy (volt ampere

(VA)) measurement

<0.1% error on active energy over a dynamic range of

1000 to 1 at 25°C

<0.5% error on reactive energy over a dynamic range of

1000 to 1 at 25°C (ADE7169 and ADE7569 only)

<0.5% error on root mean square (rms) measurements

over a dynamic range of 500 to 1 for current (Irms) and

100 to 1 for voltage (Vrms) at 25°C

Supports IEC 62053-21, IEC 62053-22, and IEC 62053-23;

EN 50470-3 Class A, Class B, and Class C; and ANSI C12-16

Differential input with programmable gain amplifiers (PGAs)

supports shunts, current transformers, and di/dt current

sensors (ADE7169 and ADE7569 only)

2 current inputs for antitamper detection in the ADE7116/

ADE7166/ADE7169

High frequency outputs proportional to Irms, active, reactive,

or apparent power (AP)
